  1. Yep...Can see the attraction...(laughing gas?)
  2. How does the pump maintain a seal under such high pressure? The reason why I ask is any kind of sealing lubricant getting into your lungs....
  3. Ditto considering around 3000psi is required for a dive cylinder. Maybe a completely sealable cabin, a air compressure pump and a hatch you can open in the hull...a moon pool!!?
  4. Covered this year's ago doing the open water. As I remember it has to do with the amount of air we exhale. I think its about .4 of a litre. The lungs hold about 6 litres so if the snorkel was too long, you would be rebreathing your CO2 which would start to catch up with the oxygen levels in your lungs. The CO2 level is whats dangerous, no so much the oxygen. Sorry, doing this from memory. You would need a way of expelling your Co2...completely.
  5. If it has N2K there are options. A MFD should control it.
  6. I think its not just nature making sails that way!!...
  7. I must admit...if flares become compulsory...and seersucker shirts, there is no hope of rescue!

  9. Morse was the first victim. Where voice simply can't be heard, morse usually got through, now obsolete. Then the requirement to even have GROC officers went, early 90's. All a result of GMDSS. Pick up a phone now and dial home. The satellite providers must be making a packet. Ships are still required to carry HF capable coms, the military still uses HF but mostly highly compressed digital or spread spectrum. Wait til there is a GIANT solar flare the likes of which wiped out power in North America in the 1920s. Satellites are supposed to be EMP protected....yeah right. The future of marine coms
  10. Those that actually have a RROC will remember the requirement to maintain watch on 2182 for 5 minutes past the hour in NZ. Ships wireless operators did the same on VHF 156.800 and I believe most GROC holders on ships today still do so even though the position has officially been disestablished by the GMDSS, holders of a STCW95 still keep watch on radio. The US required ships signals officers to do a watch on the half hour and on 500khz too even producing a wireless room clock. Today? Who knows but if you have a working VHF and a watch, can call on the hour or half hour til 5 minutes past, the
  11. The water is IN the fuel we buy. Is it a new thing? Not sure what or if there is a standard of quantity of distillate from the 70's to today but fact of the matter is, fill your tank and there will be water in it.
  12. Why don't the fuel companies add it????
  13. I second that. PLBs are essential but that doesn't "sink" in for those going out of VHF range with the wife and kids in a tinny. Most take a cellphone but how many have it in a pocket and not a waterproof bag? DSC is looked upon here as unnecessary even though CG unofficially have it. MNZ needs to do a re-think on its use here.
  14. Yeah, been scrapping the paint off the yanmar parts Ive bought...still havent found the gold underneath.
  15. As was said, there is water IN the diesel you buy. Not sure how much, may depend on service station but with regular use and the fact that the fuel is continuously being mixed through cornering and breaking, its generally not an issue for most road users. Not the same for a lot of marine users who sit about in marinas. Over time the water component seperates and we all know the rest! I believe rigging up your own fuel "scrubber" is the way to go. A pump and filters cycling fuel from and to the tank on a regular basis keep the shite and water out.
  16. Just been through all this in here (to some depth!). http://crew.org.nz/forum/index.php/topic/16245-sheeeit-diesel-bug/
  17. Another thought, voltage drop. If the TP isnt getting a good supply through a bad connection, everytime the motor operates it will rob the fluxgate of power.
  18. As IT says but before you bin it are you able to pull it apart? Had a old navico that did the same and found the problem. A fluxgate needs to sit as level as possible to operate as even 1 degree of tilt is about 10 degrees of error! They should sit on in a gimbal which allows it to stay horizontal when heeled over and over time the can either stick of simply not tilt! A bit of silicon spray, give it a shake and it might just work. Did for me but wont last that long as the gimbal pivot pins have probably worn over time.
  19. Have a digital thermo thats been sitting in the bow junk box and decided to stick the little probe suction cup on the alt. Interesting! 1200rpm, charging 13.8 which crept up to 14.1v at about 30amps. Temp rose to 34c in about 10mins and could smell burning! Bought revs up to 1900 and temp drops to 32, no more smell. Back to idle then shut down. No smell but watched temp rise to nearly 40c! OK, that's not "hot" but whats going? The alternator is definitly poked, that I know, just seems strange!
  20. Just ran about 60lts out from the fuel drain in the bottom of the tank through a pump, cheap Chinese inline filter and a Griffin 2micron filter water separator. Got some dirt then ran clean for an hour. Peace of mind knowing the fuel is now mostly clean, no water and the fuel master stuff had worked? I'm wondering if I actually had the bug in the first place? I read that the water in diesel is actually in there when you buy it! Has little to do with condensation. It separates over time but isn't an issue for trucks etc due to the regular use and fuelups.
